IMPROVEMENT IN LAWN-ROLLERS.

Specification forming part of Letters Patent N 166,915, dated August 24,1875; application filed May 3, 1875.

- State of New York, have invented a new and useful Cement Lawn-Roller;and I do hereby declare that the following is a full, clear, and

exact description thereof, reference being had to the accompanyingdrawings making part of this specification, in which- Figure 1 is a topsectional view of my invention. Fig. 2 is an end view of the roller.Fig. 3 is a perspective sectional view of one head and one end of theaxial rod I).

The object of this invention is to provide a lawn-roller that shall besubstantial and durable, and as heavy as desired, and that may beafforded at a fraction. of the cost of either stone or iron. It consistsin the employment of a roller formed of cement, strengthened andprotected by an axial rod and metallic heads molded in the ends.

The roller A is formed in a mold, preferably composed of a cylindricalcase divided longitudinally and suitably clamped together, and one endfitted into a follower-board. The-metallic heads G are composed of arim, 1", hub h, and two or more spokes, a. These parts are each beveled,as shown in the sectional portions of Fig. 1, the dotted line 00 in Fig.2 indicating the direction of the section shown at the lower end of theroller in Fig. 1, and the dotted line a that shown at theupper end. Iprefer to bend the axial rod D, as shown in Fig. l, to prevent thepossibility of its getting loose by use. One end of the rod D isinserted through the hub h of one of the heads G, and then placed uponthe follower or mold board, and the case adjusted around them. This headG is placed with the thin edge of the rim 1' and arms a downward. The

cement is tamped in, filling the spaces between them and around the rodD, until the case or mold is filled. The other head is then placed uponthe rod D, and forced down into the upper end of the case, and thecement struck off to the outer face of the spokes or arms and rim of thehead.

This upper head may be adjusted upon the rod, and within the end of thecase, before the filling of the mold is commenced, if desired, whichwould avoid the necessity of providing any centering support or guidefor the upper end of the rod.

The handle 0 is secured to the draft-straps B by suitable bolts 1). Thestraps B are keyed to the ends of the rod D by keys or pins 1;.

From a long series of varied experiments in the effort to produce alow-priced lawn-roller, I have at last succeeded in providing not only acheap one in price, but one which is also thoroughly substantial anddurable in practice.

It will be seen that the metallic heads G thoroughly protect the ends ofthe roller, and prevent the cement from being flaked or chipped oif bycoming in contact with stones or other hard substances.

The rod D may be flattened in places, or otherwise roughened, instead ofbeing bent or curved, as shown; or it may be made in two short sections.

What 1 claim as niy invention is' In a lawn-roller, the concrete body,the crooked shaft, and the dovetail heads and arms, all combinedsubstantially as shown and described.
